That depends on what you are trying to ask.First point is that heat is energy in transit - if it isn't moving from one place to another it's technically not heat. Thermal energy - the energy held by a mass due to temperature is a better term, but even that is a bit ambiguous.With that in mind...if you mean how much energy can be stored as thermal energy by aluminum, you would have to look up the heat capacity - which is approximately 0.91 kJ/kg K (the exact value depending on temperature and purity of the aluminum)If you mean how much resistance aluminum foil can provide to the transfer of heat, that would depend on the temperature gradient and how shiny the aluminum was - shiny aluminum will reflect more heat that dull/burnished aluminum surfaces.
The needed energy at 100 oC is 48751 MJ.

No, but an aluminum can can be recycled using much less energy than it takes to separate an equivalent amount of aluminum from its ore.
